to generate the 230v supply. Preference
should be to choose a generator which
produces a consistent sinusoidal wave form
with accurate voltage control.

The reverse polarity warning light may
illuminate when using a generator. This is a
normal side effect when using some types of
generator. Instead of connecting the neutral

110v difference causes the neon polarity
indicator to illuminate.

In most cases it is safe to use a generator, but
please consult the generator handbook for
further information.

Habitation relay

Habitation relays are fitted to motorhomes by
manufacturers to comply with the following
legislation:

1. The Road Vehicles (Construction and Use)
Regulations 1986 Regulation 60 - Radio
interference suppression

2. European Community Whole Vehicle Type
Approval (ECWVTA) framework directive
2007/46/EC and EU Regulation 661/2009
(General Safety) mandates UNECE
Regulation 10 (Vehicles with regard to
Electromagnetic compatibility).
